Subtraction of the esophageal artifact: effect on absolute values of Pes. Compared to PesCAL, bias (mean difference, continuous line) and precision (±1.96 SD of the difference, dotted lines) of PesVBEST were 2.1 ± 3.6 cmH2O. In individual patients, overestimation of Pes [and underestimation of transpulmonary pressure (PL)] due to esophageal elastance may be clinically significant, eventually leading to inappropriate high positive end-expiratory pressure (PEEP) levels and/or end-inspiratory lung overdistention. Pes esophageal pressure
